Therpresent invention relates to ade'vice for checking the movement of ahinged mem her in respect to its support and more particularly to a doorcheck.

The prime object of the invention resides in the provision of a hingedstructure check mechanism of this nature wherein the hinged meinberisurged to a'n'ormal position fromi which it' may be moved toa limitedpredeterminedexte'nt. Another very important object of the 1nstructurecheck mechanism ofthis nature including means between the hingedstructure and a support for urging the hinged structure to-apredetermined position, the connection between said means and saidsupporting structure being of a slidable nature and capable of beingheld in a predetermined po sition for normal operation.

. A further important object of the invention resides inthe provision ofa hinged structure check mechanism of this nature possessing 'meansforholding the hinged structurein a predetermined position against thenormal urge of the mechanism.

" A still further very important obj ect of the invention resides in theprovision of a mechanism of this nature possessed of an exceedinglysimple construction which is both strong and durable, inexpensive tomanufacture, easy to apply, convenient to operate or adjust,

' and otherwise thoroughly efiicient and re;

liable inits use and operation.-

With the above and numerous other objects in View aswill appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination, sub-combination and arrangement ofparts as will be hereinafter more fully de scribed and claimed. In thedrawing:

Figure 1 is atop plan view of the me'cha nism embodying the featuresofthis invention showing the same associated with a supporting structurewith a hinged member mounted thereon,

Figure 2 is a sectional view t'akensubstantially on the line 22 ofFigure 1,

Flgure 3 is a sectional view taken substantially on the line 33 ofFigure 1', Figure 4 is a sectional view taken substantially on the line4-4 of Figure 1, Figure 5 is a perspective viewof a rail, 4 Figure 6 isa perspective view of a slide.

' preferred structure and do'not Referring to the drawing in detail itwillbe seen that the numeral 5 denotes a supporting structure and thenumeral 6 a hinged member which will be referred to in the presentexemp-lification of the invention as a wall and door'respec'tively. Thedoor 6 is hinged to the wall 7 for the purpose of closin r a door way.The parts thus far described, of course, are conventional and may be ofany form a part of-the present invention.

The numeral 8 denotes a .rod slidable in a tube 9 one end of which-isopen to'receivethe rod 8 While the other end is-closed and has formedthereon a pair of spaced parallel'ears 10 A spring 11 is disposed in thetube 9 andimplnges against the inner end of the rod 8,. and the closedend of the tube 9. A bracket denoted generally by the letter B connectsthe outer end of the rod 8 with the door 6 preferably adj acen't, thetop thereofand the intermediate portion thereof considered horiszo1'1tally;,. This bracket B comprises a U- shaped section 12 whichterminates in outwardly directed ears 14 secured to the door by suitablefastening elements The bracket further comp-rises a second U-shapedsection 15 one end of which terminates in a laterally extending curvedextension 16., The bights of the sections 12 and 15 are connected by arivet 17 or other suitable means. The outer end of the rod 8 terminatesin a latwhich extends through openings in the ends of the sides of thesection 15 thereby hingedly connecting the rod 8with the section 15. Ihave therefore provided a connection between the-door and the rod 8 i aAn elongated rail bar is secured to the wall 5 toextend horizontallythereof or at right 'anglesto the axes of the hinges 7. This rail ispreferably formed-of a single sheet of metal bent to provide a U-shapedcross sectional formation so as to include a bight plate 21 having aside plates 22 projecting outwardly and preferably perpendicularly tothe plate 21 at the upper and lower edges thereof. The side .plates 22merge intoflanges 23 and 24, the former extending upwardly and thelatter extending downwardly. The flange 23 at itseral bearing 18 forreceiving a pivot pin 19 4 ends is provided with a. pair of inwardlyextending stop lips 25 and on its edge adjacent one en with a notch 26.'A slide S preferably comprises a sheet 27 bent over upon itself at itslongitudinal edges to provide flanges 28 extends between spectively.

and 29 for receiving the flanges and 24 re-.

Alu

31' projects from 'the sheet a 27 of the slide between the cars 10 and apivot pin 32 o enin' sin saidfiears and said lugs to hingedly connectthe slide with the tube 11. A latch 33 is in the form of a rod havinaneyem at one end and a lateralextjen'slon 35 at the other end. A ivot36 on emplification ofthe inventipn' it will be'seen that to open thedoor 6 the spring 11 must'be compressed in the tube 9 because of thesliding of the rod 8 into said tube and therefore as soon as thedoorisreleased it will return to a closed position b the expanding ofthe spring forcing the r0 outwardly of the tube and thus the door willnormallymaintained in a closed position. I a It willfurther be seen thatby opening the door a predetermined distance the curved ex= tension 16may be brought into contact with the bail 38 so as to swing the bail 38upwardly until it slips over the upper end of the extension-16 and thenthe door will be held in an open position. In this open position withthe parts disposed asindicated in the drawing the door would extend atapproximately right angles to the doorway. If it is desired to 0 enthedoor still farther the latch 33 may be li ted out of the notches 30and 26 and the slideS slid along the railR. It will be seen that thestops 25 prevent the slide from coming off the When thedoor is wideopen'andagainst the wall it will beheld fast to the wall by a latch orhook which-is fastened to the wall and which engages the door so that itwill remain stationarylxand not be affected by winds or storms.

A consideratiomofthe cooperants in their essential functional.corelationship in the present exemplification of the invention willmake it quite apparent that the mechanism is not limited tothe use witha door but is adaptable'to anyhinged structure for maintaining the.sanie in a predetermined position. I, therefore il o not wish to belimited in any way to the' .particular utility brought out in thepresengt'g 'exemplificatiofi. It is further to beunderstood that'thepresent example of the invention exclusive of the wall erence onlmovement thereof.

engaglng with the extension and ineans and door has been disclosed byway of pref- Q since in actual practice it attains theeatures'of-advantage enumerated as desirable inthe statement of theinven tion and the above descri tion. It is quite apparent, however,that c anges in the details of construction, and in the combination andarrangement of parts may be resorted to wi hout departing fromtheflspirit-or scope of the invention as hereinafter claimed orsacrificing any of its advantages. y

Having thus described my invention, what I claim as-new is:

l. A hinged structure check mechanism of the class described comprisinga pair of slidably'connected members,-means urging the members inextended relation to each other, -means for connecting one of saidmembers to a hinged structure,'and slidable':

means for connecting the other member to a fixed structure, saidslidable'means comprising .a releasable mechanismior preventing 2. Amechanism of theclass described comprising a pair of slidably connectedmembers, a slide hingedly connectedv with one of the members and-formedfrom a plate having; overhanging flanges, a rail of elongatedconstruction flanges to be received in the first mentioned flanges, ahinged bracket out-he other member, and means of a releasable nature forholding'the slide against movement on the rail. f

3. A mechanism of the class described comprising a pair of slidablyconnected. members, a slide hingedly connected with one of the'membersand formed from a plate having overhanging flanges, a. rail of elongatedconstruction, flanges to be received in the first mentioned flanges, ahinged'bracket on the other member, and means of a releasable nature forholding the slide against movement on the rail, said means comprising ahinged latch, said slide and said rail having registrable notches inwhich the latch may engage to prevent movement of the slide on the rail.

4.. A mechanism of the class described comprising a pair of slidablyconnected members, means urgin the members to. a predetermined positionin relation to each other, a

bracket hingedly mounted on one of the menr 110- ,bers' and having acurved extension, a bail hingedly mounted on theother'member for formounting said other member.
